Concept that origin of fecal pollution can be traced using microbiological, genotypic, phenotypic and chemical methods has been termed as microbial source tracking. MST is a sub discipline of environmental microbiology that focuses on differentiating the sources of fecal contamination hitherto not achieved by use of by use of traditional indicators.

DEF

A naturally occurring monoclinic mineral of hydrated silicate of magnesium which covers a wide range of products of diverse composition, shape, purity and brightness, occurs in foliated, granular or fibrous masses, appears usually under the form of a white, apple-green, gray powder or of transparent laminae or plates, with a characteristic soapy or greasy feel and a shining lustre ...

... used in ceramics, in cosmetics and pharmaceuticals, as a filler in rubber, paints, soap, putty, plaster and oilcloth, as a dusting agent, as a lubricant, in paper, in slate pencils and crayons and for electrical insulation.

OBS

Talc exists in three varieties: foliated, massive (steatite or soapstone), and indurated (talc slate or schist). Compact, massive varieties may be called steatite in distinction from the foliated varieties, which are called talc. Soapstone is an impure variety of steatite.

Record 5 2010-03-08

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Atmospheric Physics
DEF

Atmospheric temperature extending from the earth’s surface to the tropopause.

CONT

The diurnal variation of the tropospheric temperature on one day in August 1998 at the tropical station Gadanki(13. 5° N, 79. 2° E) has been studied using the MST radar technique. The diurnal variation of the temperature revealed a prominent diurnal variation with the peak in the afternoon hours increasingly delayed in altitude. The tropopause temperature and altitude exhibited a clear diurnal cycle.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Physique de l'atmosphère
CONT

Puisque la température de la troposphère (partie basse de notre atmosphère, dans laquelle se trouve les nuages) diminue avec l'altitude, les nuages de haute altitude (étage supérieur) sont plus froids que ceux de basse altitude (étage inférieur)!

CONT

Normalement, les stations canadiennes constatent que l'ozone atteint son épaisseur maximale en mars (moyenne tenant compte de facteurs climatologiques), après quoi elle s'appauvrit tout au long du printemps et de l'été, pour atteindre son niveau le plus bas en octobre. Ce cycle est attribuable à des phénomènes atmosphériques à grande échelle. On enregistre également des variations locales bien plus rapides au cours d'une même journée, à la suite de changements dans les variables météorologiques, comme le vent, les configurations de pression, les températures troposphériques et stratosphériques ainsi que la hauteur de la tropopause.

They are often stamped "MST"-Multi Service Tyre-and are "E" marked with road speed ratings on the tyre wall.
